JOSEPH HENRY NUTO GUILFORID, OF \VHIGHAM, GEORGIA.

FlSH-PLATE-FASTENING MACHINE.

SPECIFICATION forming part of Letters Patent No.-313,418, dated March 3, 1885.

Application filed January 7, 18:34.

To all whom, it may concern..-

Be it known that I, JOSEPH HENRY NUToN GUILFORD,of Whigham, in the county of De catur and State of Georgia, have invented a new and Improved Fish-Plate-Fastening Machine. of which the following is a full, clear, and exact description.

My invention relates to improvements in fish-joint-fastening machines; and it consists in the peculiar construction andarrangemeut of parts, as hereinafter fully described, and pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of my improved machine, and of a fish-joint to which the machine is applied for screwing up the nuts, on line a." x of Fig. 2. Fig. 2 is a plan view of the machine with a detail in section. Fig. 3 is a section on the line yy, Figs. 1 and 2. Fig. 4 is an end elevation. Fig. 5 is a detail of the wrenclradjusting devices. Fig. 6 isa section of one of the wrenches, show ing the application of a screw-cutting die to run over the screw-threads of the bolts when required. Fig. 7 is an end elevation of Fig. 6. Fig. 8 is a section of one of the wrenches, showing the application of a reamer to bore or ream out and enlarge the holes of the fishplate when required. Fig. 9 is an end elevation of Fig. 8. Fig. 10 is a plan view of a feeding-clamp to be employed with the drill or reamers when used for boring the rails and enlarging the bolt-holes in the fish-plates; and Fig. 11 is a section of the feeding-clamp and the fish-joint.

I mount a couple of socket-wrenches, a, on spindles b, arranged side by side horizontally in a bed-frame consisting of cross-bars c and side bars, d, and having the side bars,d,fitted at one end,e, to the shape of the side of a rail, f, and provided with a clamp to clamp the frame fast to the side of the rail, said clamp consisting of the fulcrum-stirrup linksg.yokelever It, bearing-bar i, and the holding-pawlj. The fulcrum-links g are pivoted vto the side bars, (I, of the frame at In, and extend over across the rail f to the yoke-lever h, to which they are pivoted at Z. The bearing-bare is attached to the lower ends of the arms of the (Model-l yoke-lever to bear against the fish-plate m,and the pawl-bar j is pivoted at n to the upper end of one of a pair of housing-frames, O, and has a notched portion; 19, extending through a slot, q, of the upper end of the yoke-lever, in which it is secured,when adjusted, by akey,

ing-bar "i also has sockets t, that titon theheads of the fish-joint bolts to, to prevent them from turning when the nutso are being screwed on. The sockets t are located in the bearing-bar 1', so that they will receive and hold the heads of the two bolts on one side of the rail-joint while the socketwrenches a are screwing on the nuts, the spindles of the wrenches being also arranged the same distance apart as the the bolts are placed from each other in the fish joint, and they are coincident with the l sockets t to apply the nuts when the bolts are held in said sockets. The wrench-spindles b are fitted in hearings to of the cross-bars 0, so that they may be pulled back by a handle, a, and crossbar y, to place the nuts 1) in the sockets z of the wrenches, and the spindles have springs a to press them forward to enter the nuts on the ends of the joint-bolts. The cross-bar 3 pulls against the stud-pins b to slidethe spindles back. and the springs a bear against the same studs to push the spin dles forward, said springs being supported at the other end against the cross-bar c of the frame. 7

To hold the spindles back against the springs while adjusting the nuts, and for any other purpose, the bar 0, connecting handle .90 with cross-bar 1, has a notch, d, and a latch, e, is fitted on the cross-bar c to drop into the notch, said notch being so located on the bar a that it comes out to and receives the latch when the wrenches are pulled back. The wrenches a are fitted on the spindles by sooketsf, square shanksg of the spindles, and set-screws h, to enable them to be taken off quickly in case it may be desired to remove a nut that is too slack and put on another, or for any purpose. To apply power to the spindles for turning the wrenches, said spindles are each fitted with along pinion, tflwith both of which an intermediate wheel, j, gears, to which power is applied by a driver, k, on the crankshaft Z. The crank-shaft l and the shaft m of the intermediate wheel are mounted in the houss, to bind the clamp fast on the rail. The bear-.

ings 0, suitably for gearing with the wrenchspindles, so that the crank n will swing clear of the ground and the handle :0.

To apply additional power to the driving wheel is when the nuts turn very hard, the said driving-wheel is provided with staples 0 at intervals around it on one side, in which a hand-lever, 12, may be, inserted-for a purchase to screw the nuts home with a powerful thrust.

It may sometimes be preferred to use the smaller wheel j for the driver and the larger wheel k for the intermediate, and I have prepared bearings q in the housings for shaft 1, and bearings s for the shaft m, enabling the shafts to be shifted readily. In such case the two shafts will be fitted alike for the crank n, so that it may be very readily changed.

from one to the other.

This machine can be readily clamped to either side of the rail, so as to be suitahlysupported for connecting the wrenches with the nuts, with the back end of the frame resting on the ties or on the ground, and it affords a simple and convenient means of screwing up the nuts more rapidly and powerfully than can be done by hand. It is first applied to the nuts of one end of the rail-joint, and is then shifted along to the next. If preferred, one of the wrenches may be taken off and the other one used alone. Sometimes bolts a will be formed on which the threads have not been su'fficiently cnt,in which case I have a socketsc'rew cutting-die. a, to fit in the socket z of the wrenches, and be secured by a set-screw, v, to be run on the bolts, the same as the nuts are run, to properly reduce. and finish the threads; but in this case the die a will be withdrawn by turning the crank backward.

The die a may be made in two parts with connecting-screws w, by which the parts may be set as required for the size of the bolts.

For reaming out the holes of the fislrplates when it may happen that they are too small for the bolts, and also for boring out holes in the rails when necessary to fit holes corresponding to holes in the fish-plates, I provide a socket, 0 to fit the sockets z of the wrenches,

with a reamer, d, to be carried therein for turning the reamer by the hand-power apparatus, as indicated in Figs. 10 and 11, and also provide a clamp to force the reamer into the holes, consisting of the clamp-plate e",having flangesf, bearing against the ends of the socket wrenches a, and also having the flange g", turning down the side of the rail, and carrying a feedscrew, h*, by which to force the reamers in. The flangesfof the clamp-plate e are notched suitable for straddling the wrench-shafts to bear against the wrenches on each side of the shafts.

The improved machine will effect considerable saving of time and labor in the fastening of fish-plates, besides enabling the joints to be fastened more effect-nail y.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a fish-plate-fastening machine, the

combinatiomwith a frame carrying wrenches,

of a clamping device consisting of the linksg, yoke-lever h, bearing-bar i, and holding-pawl j, subst-ant ially as herein shown and described.

2. In a fish-plate-fastening machine, the combination, with the frame consisting of the bars a d and uprights O, of the shafts Z m,the gears i'j is, the spindles b b, the wrench-sockets a a, and the springs a, substantially as herein shown and described.

3. In a fish-plate-fastening machine, the combiuation,with a supporting-frame and the sliding spindles I), provided with wrenches a on their ends,of the long gear-wheels i,'mouuted on said spindles, and the gear-wheels la, substantially as herein shown and described.

4. 111 a fish-plate-fastening machine, the combination, with the spindles b I), having wrench-sockets a a and pins b, of the bar 0, having handle as and cross-bary,t1nd provided with the notch d, the springs a, and the latch e, substantially as herein shown and described.
